短时事件下的地铁乘客路径选择行为研究

Route Selection Behavior of Subway Passengers under Short-term Events

为研究轨道交通短时事件下出行者的择路行为,将在途出行者的择路行为分为3类,并引入前景理论描述其出行行为,考虑了行程时间、出行费用及换乘次数3类因素,以Logit模型为基础,建立流量加载模型。最后以广州塔地铁站为研究对象,分析地铁不经停情况下的乘客择路行为,比较了乘客对换乘次数敏感及线路换乘次数增加的影响。结果显示:当乘客对换乘次数敏感或线路换乘次数上升时,线路流量与换乘次数负相关;乘客的路径选择行为是3类因素的客观大小及乘客的主观偏好的共同结果。

In order to study the travel behavior of travelers under the short-term event of rail transit,firstly,the travel behavior of travelers on the way is divided into three categories.Then,the prospect theory is introduced to describe its travel behavior from the perspectives of three factors:travel time,travel expenses and transfer times.Based on the Logit model,a traffic loading model is built.Finally,taking Guangzhou Tower subway station as the research subject,this paper analyzes the passengers’choice of road behavior when the subway is not stopped,and compares the passengers’sensitivity to the number of transfer times and the increase of the number of transfer times.The results show that when the passenger is sensitive to the number of transfers or the increased number of transfers,the line flow is inversely related to the number of transfers.The passengers’path selection behavior is influenced by the objective value of the three factors and the subjective preference of the passenger.
